Incremental Model BY Niat Murad
Defination. • In incremental model the whole requirement is divided into various builds. • Each module (independent units) passes through the requirements, design, implementation and testing phases. • The incremental build model is a method of software development where the product is designed, implemented and tested incrementally until the product is finished. Build2build1 build3Whole requirement
• Each subsequent(coming after something in time) release of the module adds function to the previous release. The process continues till the complete system is achieved.
• when we work incrementally we are adding piece by piece but expect that each piece is fully finished. Thus keep on adding the pieces until it’s complete. block block block 1 2 3

Incremental development model:
When to use the Incremental model: • This model can be used when the requirements of the complete system are clearly defined and understood. • Major requirements must be defined; however, some details can evolve with time. • There is a need to get a product to the market early.
Advantages of Incremental model • Generates working software quickly and early during the software life cycle. • This model is more flexible – less costly to change scope and requirements. • It is easier to test and debug during a smaller iteration. • In this model customer can respond to each built. • Lowers initial delivery cost. • Easier to manage risk because risky pieces are identified and handled during it’s iteration.
Disadvantages of Incremental model: • Needs good planning and design. • Needs a clear and complete definition of the whole system before it can be broken down and built incrementally. • Total cost is higher than waterfall.
